n = -0.75
Step-by-step explanation:
Simplifying
9 + 12n = 0
Solving
9 + 12n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + 12n = 0 + -9
Combine like terms: 9 + -9 = 0
0 + 12n = 0 + -9
12n = 0 + -9
Combine like terms: 0 + -9 = -9
12n = -9
Divide each side by '12'.
n = -0.75
Simplifying
n = -0.75
